and used interchangeably in an insulated insulated. The advantage of its use in an insulated joint is, that the bars can be made of the same section throughout, withthe further advantage that the insulating and non insulating plates can be interchanged to. prolong their life and at the joint and keep the though not necessarily, made of softer steel, than that of the rails and bars, so as to act ,bars of abrasion. g

"Our invention also includes the'use of two kinds of spacing members when desired. These spaclng'members are interposed be-' tween adjacent bars, or between the bars urpose of forming a rigid metallic bearing tweenan outer bar and the rail and thus bearing face while the other kind are insulating spacingmembers for resisting the forces between adjacent metal faces, thus also protecting the intervenin insulation from being crushed, either by tie pinching action of the bars in service, or by undue tightening of the bolts. These latter maybe made of any hard or rigid insulating material, and ma 'be made separate from, or may be einbedde into the insulating fiber plates. To still further increase the insulating. bearing members of the joint, wemay use one of the joint, for the purpose of making such bars act together. These tie bars are insubelow the rail base, or at-both places. These bars may be wide enough to envelop any desired portion of the outside bars, and may be provided with bolt seats or through-bolts ba of the rail.

modifications, a number of which have been illustrated 11) the drawings, which will now be described.

In those drawings, the numeral 2 wherever,

' indicated at 7, to receive the outer bars 4,

which bear against the under sides of the I rail heads at their upper edges, and are connected by bolts both above and below the rail base. In this form, the insulation 5 is placed between each. of the bars 4 and the inner splice bar, and-the splice bar is also insulated from both rails.

In the form shown in Fig. 2, one of the outer bars 418 shown as a short bar, which terminates at the base-flange of the rail; no

insulating material is used between it and the splice bar and the splice bar makes me tallic contact with the rail through an intervening metallic plate, which is employed so that the section of the bar may be uniform opposite both rails. In both forms 1 and 2,

23 are splice bar bolts extending through the splice bars and the rails.

Fig. .3 shows a side elevation, and Figs. 5 and 6 are cross-sections of a joint illustrating the use of the tie bars 8, which connect the outer bars 4 both above and below the rails and terminating short of the upper bolts. They also have lower members which terminate above the lower bolts, and may or 'may not support the wooden blocks 9. In

this case the inner splice bars are about the same length as the outer clamping bars.

In Fig. 4 we show a form similar to Fig. 1, except that the upper cut-out portion' of the inner splice bar is deeper and the depending flange is made longer in order to provide sufiicient metal to furnish stiffness for the bar. Instead of being insulated from both rails, the inside splice bar contacts directly with one rail. The deep cutting or recessing of the splice bar allows the outer clamping plates or bars to be extended in horizontally above the level of the rail base flanges, thus providing vertical bolting faces, which allow shorter bolts as shown in Figs. 5 and 6, In this case, the insulation extends lmrizontally between the horizontal member of the clamping plate and the splice bar.

gas

A non-insulating spacing plate is used between the bars on one side'of the 30st 1nstead of insulation, in order to maintain tinsame section of the bars throughout.

In Fig. 7 the right-hand portion of the. splice bar extends below the head of the rail so that two of the bolts extend through this inner splice bar 3. Thence. the upper edge of the splice bar is inclined down wardly as indicated by the dotted lines. to a lower level; and is notched to clcarihe bolts 6. it being extended upwardly between the bolts to give greaterstifl'ness. In this form the left-hand portion of the joint is :similar to that of Fig.3, exceptthat the bar 8 18 not used, the plate 4 extending straight up to the head of the rail as shown so in F ig. 9. The right-hand portion of the jointis the same as the left-hand portion, except for the inclining of the upper edge of the splice bar,,a;t d the cutting away on cur ed lines of the dzpending flange and of the plate 4. T iiscutting away allows a closer spacing of the ties, and may be used on either one or both sides'of the joint.

Figs. 9, 10,11, 12, 18, 14, 15, and 16, show forms in which the inner bars are shown as of various forms, either extending inwardly underneath the base flange of the rail to form a chair orsupport therefor, or projecting downwardly out of contact with the rail base to support a block or other supporting member. Thus, Figs. 9, 11 12 and 13 show forms in which the inner bars are extended horizontally inwardly beneath the base fi nge to form the rail chair or seat; while Figs. 10, 15, and 16 show the flanges projecting downwardly and inwardly out of contact with the rail base to supportthe mock or supporting member 9L In Fig. 12 the plate or bar 4 has an intermediate downward extension 26 which contacts with the rail base and performs the function of the spacing pieces 11 which are shown in Figs. 18. 1.9, 20 and 21.

Fig. 8 shows another construction, in

which the outer bars 4 are recessed to receire comparatively sl= )rt, small inner splice bars, which extend across the joint as shown,

and are pocketed within the outer bars.

Fi s. 17, 18, 11 20, 21, 22, 24, 25. 20, 2'? and 28 show various forms of the inner and outer bars. which will be clearly understood by reference to the drawings without detailed description, it being understood that in each case the inner bars extend continuonsly across the joint between the two rails while the outer bars are separa e bars, which may be of the forms illustrated in either of Figs. 1, 2, 3, 4, 7 and 8. Figs. 12', 18, 19 and 20 are sectional views showing forms of joints with side elevations similu r member the extra insulation surfaces into action and thereby increase the insulating area by causin the outer plates to move with the rails in either direction up or down as the load passes from one rail to another, as .would be the case with the outer bar as shown in Fig.

12. Fig. 1i? shows. the insulating spacing. members 11 interposed between the inner bar and the upper surface-of the rail base. 1 1g. 18 shows one of these members 11 in? terposed betwe n the inner and outer bars,

and also a second and larger metallic member 11 extending through the inner bar and interposed between the outer bar and the upper surface of the rail base, with surrounding insulation 12. Fig. 19 shows a similar metallic spacing member 1.1 interposed between the flange 13 ofthe outer bar and the upper surface of the base flange of the rail; Eig. 20 shows spacing members similar to those of Fig. 18, and Fig. 21 shows a large metallic spacing member 11 similar to that: of rigs. 18 and 20.

It. will be noted that. the outer bars are shown as provided with grippin" surfaces forthc bolts of various characters, eitherby forming separate flanges l4.- thereon, as in Figs. 21 and 22, or by milling, out a recess as in Figs. 17, 18, 19 and 20, the last having an insulated washer; or by forming specially shaped .faces 15 therefor, as in F igs. 23, 2%, 25;, 26, 27 and 28.

In Figs. .23, and 24 we show the outer bar as having a depending vertical bolting flange 20, to receive through-bolts which extend across beneath the joint, and these outer members are also provided with inwardly extending horizontal flanges 24:to

support the inside chair bar for the joint.

-In 'Figs. and 126 ordinary angle bars are employed without depending flanges, and the outer bars are extended inwardly and horizontally, as shown at 25, to form metallic seats, which contact directly with the base of the rail. In this case there is a metallic seat between the outer bars and the head-of the rail and the base of the rail, no insulation being required.

In Figs. 97 and 28, the construction is. somewhat similar to that of Figs. 25 and 26, exc pt that the depending flanges 20 are empluyed to receive the through-bolts benemh the joint.

c Fig. 29 shows 'aiorm of joint in wh ch the iiin'er bars are provided with interiittingbase portions 16, upon which the rail base is seated, with intervening insulation, and which are slotted as indicated at 17 to receive a vertical portion 18 of the outer bars. The lower portions of the outer bars are carried inwardly underneath the rail base, and the interfitted base portion 16 of the inner bars, and are connected by bolts 19 seated in the depending flanges 20 of the outer bars.

Figs. 20 and 31 show other forms of the joint, in which both the inner and outer bars are carried around-the rail base and extend below the same, in such a way as to provide' a broader insulating bearing surface and give greater flexibility.

In all the forms heretofore refrredto, at least two outer bars are employed at each side of the rails. In the modification shown n Figs. 32 and 33, a single outer bar 21 1s employed at each .side of the rails, being I bolted through to a similar bar at the opposite side, the bars at the two sides having heads bearing against different rails.

F ig. 34 shows a form similar to forms 32 and 33, except that the outer bar 21 is not.

inclined and does not extend across the joint.

In this case, both of the outer bars are bc- .neath the same rail head, and the depending flange of the splice bar does not extendequally on both sides of the joint, but is Y placed directly under the notched portion which is almost wholly at one side of the joint. In Fig. 34 the inner splice bar has direct contact with the head of the rail in the left-hand port-ion, while in the right hand portion it is insulated therefrom, the

inner face of this portion of the bar being offset or recessed to receive the insulation.

In Figs. 32 and 33, a non-insulating plate is employed between the left-hand portion of the splice bar and the rail, this being interchangcable with the insulation to make the splice bar similar on both sides.

The advantages of our invention resulting from the use of the inner and outer bars of the character described, willhe obvious to those skilled in the art. The strains in the joint are transmitted from narrow unyielding surfaces to broad flexible faces, and each rail has a separate bar or plate which can be tightened against it to take up wear. Efi'ective insulation is provided for, together with protection against the cuttingof the insulation, while the joint as a whole is an exceedingly stiff and secure one, which is well adapted to modern conditions of traflic.
